for-each and value-of (tree menu)

Hello everybody,

I'm having a problem in my XSL code. My XSL file get an xml as input and
derives an html. In the output html I'm trying to do a tree menu, and the <h4>
html tag is the initializator of the button in menu, i.e. when I click in this
button, the menu open, like this "+" of xml.
The problem is that, as the h4 is after the for-each, it's appearing just in
the first value. So, the menu is ok (open) just for the first value. Ex:
goal
   +question1
   +question2
If I click on question 1, open or close his submenu. If i click on question 2,
should appear his submenu, but it open or close the menu of question 1 too.
Can anybody help me? Thanks a lot.

<xsl:for-each select="gqmroot/goal">
	<h4><xsl:value-of select="@titleGoal"/></h4>
		<ul>
		<li><xsl:for-each select="question">
			<h4><xsl:value-of select="@titleQuestion"/></h4>
				<ul>
				<li><xsl:for-each select="metric">
					<h4><xsl:value-of select="@titleMetric"/></h4>
						<h4>
							<xsl:value-of select="unparsed-text(@ChartLink)"
disable-output-escaping="yes"/>
						</h4>
				     </xsl:for-each>
				</li>
			        </ul>
			</xsl:for-each>
		</li>
		</ul>
</xsl:for-each>
